Popis:	The mass spectra of methyl- and halo-substituted 2- and 4-aminopyrimidines at an ionizing electron energy of 70 eV were studied. It is shown that the molecular ion of the investigated compounds corresponds primarily to the imine form. This structure determines the principal direction of disintegration, which proceeds through the formation of pseudomolecular ions with an imidazole or pyrazole structure, depending on the position of the amino group in the pyrimidine ring.
